13.4 DC Flash Write Specifications
This table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and –40
°C < T
apply to 5 V, 3.3 V, or 2.7 V at 25 °C. These are for design guidance only. Flash Endurance and Retention specifications are valid only
within the range: 25 °C±20 °C during the flash write operation. It is at the user’s own risk to operate out of this temperature range. If
flash writing is done out of this temperature range, the endurance and data retention reduces.
